Getting Started

Worker Model

By default, the web service starts with one worker process. Each worker handles documents in a single-threaded mode that means that it can process only one request at a time. The number of workers is limited by available hardware resources and the license type.

For the Face SDK web service, Online and Software licensing models are available.

The recommended machine settings are 1CPU and 3Gb RAM per worker.


The version A.B.C.D-cpu/gpu is composed of:

  • A.B for the Regula SDK version
  • C for the neural network version
  • D for the service wrapper version
  • cpu or gpu for the version configuration

For example, a version 3.2.325.304-gpu should be interpreted as follows:

  • 3.2 is the Regula SDK version
  • 325 is the current neural network version
  • 304 is the web service wrapper version
  • gpu is the version configuration
